Overview of this book

Do you want to transform data into captivating images? Do you want to make it easy for your audience to process and understand the patterns, trends, and relationships hidden within your data? The Data Visualization Workshop will guide you through the world of data visualization and help you to unlock simple secrets for transforming data into meaningful visuals with the help of exciting exercises and activities. Starting with an introduction to data visualization, this book shows you how to first prepare raw data for visualization using NumPy and pandas operations. As you progress, you’ll use plotting techniques, such as comparison and distribution, to identify relationships and similarities between datasets. You’ll then work through practical exercises to simplify the process of creating visualizations using Python plotting libraries such as Matplotlib and Seaborn. If you’ve ever wondered how popular companies like Uber and Airbnb use geoplotlib for geographical visualizations, this book has got you covered, helping you analyze and understand the process effectively. Finally, you’ll use the Bokeh library to create dynamic visualizations that can be integrated into any web page. By the end of this workshop, you’ll have learned how to present engaging mission-critical insights by creating impactful visualizations with real-world data.

Overview of Plots in Matplotlib

Plots in Matplotlib have a hierarchical structure that nests Python objects to create a tree-like structure. Each plot is encapsulated in a Figure object. This Figure is the top-level container of the visualization. It can have multiple axes, which are basically individual plots inside this top-level container.

Figure 3.1: A Figure contains at least one axes object

Furthermore, we again find Python objects that control axes, tick marks, legends, titles, text boxes, the grid, and many other objects. All of these objects can be customized.

The two main components of a plot are as follows:

  • Figure

    The Figure is an outermost container that allows you to draw multiple plots within it. It not only holds the Axes object but also has the ability to configure the Title.

  • Axes

    The axes are an actual plot, or subplot, depending on whether you want to plot single or multiple visualizations. Its sub-objects include the...
